Namespaced global event emitter
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Sparkles exports a function that returns a singleton `EventEmitter`.
|
||
|
|
This EE can be shared across your application, whether or not node loads
|
||
|
|
multiple copies.
|
||
|
|
|
||
|
|
```js
|
||
|
|
var sparkles = require('sparkles')(); // make sure to call the function
|
||
|
|
|
||
|
|
sparkles.on('my-event', function(evt){
|
||
|
|
console.log('my-event handled', evt);
|
||
|
|
});
|
||
|
|
|
||
|
|
sparkles.emit('my-event', { my: 'event' });
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
### sparkles(namespace)
|
||
|
|
|
||
|
|
Returns an EventEmitter that is shared amongst the provided namespace. If no namespace
|
||
|
|
is provided, returns a default EventEmitter.
|
||
|
|
|
||
|
|
### sparkles.exists(namespace);
|
||
|
|
|
||
|
|
Checks whether a namespace exists and returns true or false.
|
||
|
|
|
||
|
|
## Why the name?
|
||
|
|
|
||
|
|
This is a "global emitter"; shortened: "glitter" but it was already taken; so we got sparkles instead :smile:
